IMPROVEMENT IN MOULDING- PIPE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, FREDERICK SHIOKLE, of St. Louis, in the county of St.-Louis, and State of Missouri, have made certain new and useful Improvements in Devices for Moulding Pipe, and for similar purposes and I do hereby declare the following to be a full and correct description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of this invention is to form atrue and proper mould for castmg'pipes, columns, or similar bodies, especially suchas are of great size and weight;

and

The nature of said invention is in arranging the mould-frame or flask upon movable' tables, by which said frame or flask may be adjusted about the pattern, this being, at the same' time, supported in proper vertical position upon a spindle, secured tov a stationary bed-plate.

'lo enable those herein skilled to make and use my said improvements, in their usual application in pipemoulding, I will now more fully describe the same, referring to v Figure l as a longitudinal sectional elevation; to

yFigure 2 as a plan 'of the tables and bed-plate, as seen after the liasks and cores are lifted off.

I form the flask in halves, L and L', supporting each half flask upon a table, M or M. vertical position of the flask, said parts are held by pins 'm and m', respectively, or by clamps.

The tables M and M move longitudinally ou the ways or slides N, and to regulate and effectuate said movement, a screw-shaft may be used, to move a proper nut, connected with each of said tables, or a rack and pinion, or similar devices may be employed.

Between the slides N, and strongly connected therewith, to form a united frame, is arranged the centre plate O, having the vertical central spindle I.

Resting upon the`bed-plate O, and guided by the spindle P, is the pattern-frame Q. Said frame Q is a stout rectangular frame,for supporting the pattern Q. The arrangement of these parts is such, that by any usual derrick orv hoisting-device, the 4frame Q and its 'lo insure Ma proper pattern, as well as the flask-halves L and L', may be with `the sand in' the l'lask L and L', and thus leave welldefined edges, so that when the flask-halves are afterward joined, the joint will be comparatively imperceptible.

This movement of the pattern will ,be eifected by cam, or other devices, withinvthe same, acting (under power of the operator) to move out the semicylinders o f the pattern Q from the frame Q, or recede the same into said frame. y

To make a proper joint at the base, the flask L L has an annular rim,ll, with which the pattern Q con'- nects nicely, when the parts are in close adjustment.

In the use of my said improvements, after the sand has been properly rammed in between the flask and pattern, the pattern Q being receded, the sand in the liask forms the mould-surfaces, the dividing edge at `the vertical flame Q being nicely preserved, (by the operation of withdrawing the pattern into the frame.) lheask-halves are then disconnected from each other, vby releasing the usual clamps, or other .holding-devices, whereupon the tables M and M are moved away from the central frame Q, by the devices as beforel in-` dicated, and the frame Q, and its pattern isthen lifted oli' its spindle and support the flask-halves are then again moved to a joint, and securedtogether, whereupon they may also be lifted off' the tables M M', to be dried, and used in the usual manner.

Having thus fully'described my said invention, l `What I claim, is- 1 1. The flask LL', supported vertically upon sliding tables M M', substantially as set forth. 2. Supporting thev pattern-frame Q by the centreplate O and-,spindle P, substantially as set forth.

In witness of said invention, I have hereunto set my hand in the presence of- Witnes'ses: FREDERICK SHIOKLE.
